RAILWAY DRAFT-RIGGING.

Application filed March 9, 1914.

useful Improvement in Railway Draft-Rigging, of which the concise,

following is a full, clear and exact description, reference being had to the accompanying drawings,

forming a part of this specification.

' y invention relates to improvements in draft rigging for railway cars. I

The object of my invention is to provide a draft rigging of efficient operation and one adapted toaflord an easy start to the railway'cars to which the same is applied.

In the drawings forming a part of this specification. Figure 1 is a plan. view, partly in horizontal section, of a draft rigging embodying my invention; Fig. 2 is a cross section on line 2-2 of Fig. 1: Fig. 3 is a cross-section on line 3-3 4 a side elevation of the draft gear; Fig. 5 aperspective view of the draft gear shell; and Fig. 6 a perspective VlQW of the rear follower.

Referring to the drawings, the numerals 7-7 indicate draft sills or parts of the carframe to which the draft rigging is applied; 8-8fri ntstop-members having the front stop-should" rs 9 9; 10-10 rear stop-incinbers havin the rear stop-shoulders 11-11.

The numeral 12 the rear end of which only is shown in Fig. 1 of the drawings, to which is secured the draft yoke 13 inclosing the front follower 14 and the draft gear 15.

The parts are supported between the sills by the tie-plate 16 suitably secured to the draft members 7-7 by the bolts 171'7.

The draft gear lfi'comprises a shell 18 having a pair of forwardly opening Clltlllfbers 19-19 in horizontal twin arrangement therein. Each of said chambers is closed at its rear end by :1 preferably integral plate 20, and rearwardly thereof'the shell is provided with the rearwardly opening preliminary spring chambers 2121. The for- 'wardly opening chambers 19 are with the internal friction faces 2222, and

pro vi ded each contains the friction elements 23 coin prising the wedge 21 and the friction shoes 25-25 and the spring elements 26, preferspring 27 and an inner spring forwardly seated against the friction ele- Specification of Letters Patent.

In. each of the preliminary spring chambers 21 mounted the pre iminary spring members 29, each comprising preferably an outer spring 30 and an inner spring 31, the said springs being seated against the'plate 20, and

:52 and about the bosses 33 with which the inner face of the rear follower is provided. The rear follower'32 comprises a plate 3+1 of sufficient dimensions to close the rear ends of the preliminary spring chambers 21-21, and having a forwardly extended collar 35 adapted to surround said preliminary spring chambers and to engage the shoulder 36 with which the rear end of the shell is provided'to limit its forward movement in re lation to the shell 18. The collar provided above and below the shell 11% with the forwardly extendedwviiigs 38- 38, the said wings in preferable construction be ing conformed to the adjoining portions of the shell 18, which in preferable construe tion is provided above and below with the medium grooves 3:39 within which the wings 38 are adapted to reciprocate. wings 38 are each provided with a slot-40 adapted to register with a slot -11. vertically extended through the shell 18 and between the chambers thereof- The said slots in the follower and shell are adapted to receive a vertical key -l-2 terminating at its ends within the space bet-ween the limbs of the yoke 13. In preferable CODSlTI'lH'lTlOlI the friction elements and spring elements within the chambers 19 are sisting capacity than the preliminary springs in the prelin'iiiia'ry spring chambers of the shell.

In assembling the parts of the draft gear, the preliminary springs are placed in their appropriate spring chan'ibcrs and are of a suitable length so that in assembling the rear follower with the other parts. of the draft gear the preliminary springs are placed 111% dcr an initial coi'iipres'sion before the slots in the wings 38 of the follower the slot 41 through the shell.

Thereupon, on further forward movement of the draw- 7 bar the friction andsPrin-gelements in thechambers 19 act in the usual manner, which is well understood. On rearward movement of thedraw-bar the rear follower is sto pleld t e preliminary springs are compressed ,until the rear follower engages the sh0ulder'36 of the shell, whereuponthe action of the parts within the chambers 19-49 continues in the usual well known manner.

bers and draw-bar, of a shell,

It will thus be apparent that in my device the very high capacitated friction and spring elements in, the chambers 19 may be employed, and that the compression resisting member is insured. I claim:

1. In a' draft riggin for railway cars, the

combination with dra t-members, stop-members and draw-bar, of a shell frict on elements and spring elements within the shell, a rear follower, a key and preliminary springs between the shell and rear follower,

the key slidably engaging therrear follower to the shell;

- 2. In a draft riggin combination with-dra fmembers stop-memfrict1on'ele' twin arrangement,

by reason of the prelimi nary springs an easy initial movement of preliminary springs for railway cars, the

ments and spring elements within the shell,

a rear follower, a he and preliminary springs between the she land rear follower, j,

the key passing through the shell and rear follower to hold the preliminary springs under initial compression.

3. In a draft rigging for railway cars, thecombination with draft-members sto -m embers, draw-barand yoke, of a shell avin forwardly opening chambers in'horizonta a rear follower, nary springs between lower, and a key, each chamber of the shell containing friction elements and spring elements, the follower being rovided with for-' wardly extending wings idingly connected tothe shell by'means of the key.

'4. In a draft gear for railway cars, a

' shell, forwardly openingchambers in said shell in twin arrangement, com ression resisting elements in each of sai rearwardly opening chambersv in said shell, preliminary springs in each of said chambers, aefollower and a key, the follower being provided with forwardly extending wings the shell being provided with grooves j in which said wings are adapted to reciprocate, the key passing through the shell and slidingly engaging the being seated against prelimi'- the shell and rear folchambers,
